Case: Read the following passage and answer accordingly Amines are prepared mainly by the reduction of nitro compounds. Alkyl or benzyl halide on reaction with an ethanolic solution of ammonia undergoes nucleophilic substitution reaction in which the halogen atom is replaced by an amino group. Amines are prepared from Phthalimide. Treating an amide with bromine in an aqueous or ethanolic solution of sodium hydroxide result in amines. |
Amine that cannot be prepared by Gabricl- Phthalmidie synthesis is; |
Aniline Methyl amine Ethyl amine Propyl amine |
Aniline |
Only aliphatic primary amines can be prepared by Gabriel synthesis. Aniline cannot be prepared by this method. |
